Update Collation of all fields in database on the fly

Question

We recently moved our database from our SQL Server 2005 server to our SQL Server 2008 server. Everything moved over fine, however now we are finding that we are getting col

Answer 1

The code fails to take NText, NChar and NVarchar double bytes into account. If you have NText it will fail with Ntext(16) unable to set size on NText.

For NChar and NVarChar it doubles the length, because it fails to divide size by 2.

Another Quirky little detail, is that for Nvarchar at least, -1 is not MAX, but 0 is.

This is a very very ugly hack on the code, just to illustrate the issues:
